Abstract
A scalable three dimensional printing apparatus capable of movement along three axes includes a tractor assembly movable along a selectively extendable rail component. Wheels in the tractor assembly surround part of the rail component to enable movement of a gantry bridge in a longitudinal direction along the rails. A movable printing trolley moves horizontally along a gantry bridge and has a printing column which can move vertically. Because the gantry bridge, trolley, and printing column move orthogonally to each other, users may print in three dimensions. Selective extension of the rails allows a user to alter lengthwise printing scale.
